To all-whom it may 0022067771,. I I

I Be it known that we, JOHN B. MORIN, a

' citizen of the Dominion of Canada, and

- Apparatus and Processes for'Marking FRAN 0. Soon, a citizen of the United States, residing at Mittineague, ,county of Hamp den, and State of Massachusetts, have invented new and useful ImprovementsP aper, of which the followingis a specification. This invention relates to a means for ap plying a mark to paper An ob'ect of the inventionis to-provide a marking device or attachment of thekind above alluded to, structurally independent of a paper making machine, but capable of being applied thereto and-operating'in connection therewith to treat the paperin a certain stage ofthe process of its formation.

Another object of the invention is to provide a marking device for paper adapted'to produce a pattern'on the paper of a size larger than the circumference of any roll acting upon the paper in the progress of the letter thrpugh the paper-treating machine.

Another object of this invention'is to pro- 'vide a marking device of the classdescribed, capable of being applied in a suitable machine to treat specially prepared paper. 5 a

. Another object of this invention is to provide a device of the kind described operable in .connection with, but structurally independent of press rolls in paper making or paper treating machines, whereby the device may be applied in connection withthe ordinary form of smooth press rolls and requires nospecial roll or modification of the structure of the machiner Another object of this invention is to provide a flexible strip adapted to travel through the bite of press rolls along with the paper and thus impart its, impress to the paper.

Another object of the inventlon is to pro vide a device of the class described, inexpen sive to make, simple and eflicient in its operation and capable of being easily. replaced when damaged.

A still further objectof the invention is I to provide in connection with the marking device for paper and cooperable therewith, 'a'i'neans whereby the said device may be positively, accurately and readily localized with respect to the material it is adapted to' vided .at their lower end with blocks 14 treat.

' Specification of Letters Patent. P t nmn Juinmg my'wm, Application filed May 18, 19 14. Serial No. 839,272, I l

- of a pair ofpressure rolls or equivalent device, preferably acting upon the paper, if

the device is applied in a paper making ma chine, between the beginning and the end of the drying operation, that is to say when the paper is damp but not wet; and in conned tion with theserolls a traveling belt adapted to travel through tl1e ,bite of the rolls with the paper. The invention maybe applied, however, in a machine'adapted to treat manufactured paper-the operation of .fithe' mechanism disclosed herein depending solely upon the condition of the paper and not upon the manner in which the paper at- I .tained that condition The specific modification of thezinvention disclosed in thedrawi'ngs which illustrate,

the application thereof in one of its simplest forms, relates to; a means for causing an imp'ression tobe made upon paper rolls while "the latter is-in a predetermined condition inorder to produce a relatively thin stripe in theframe are journaled drier rolls. 1 and 2,-

these rolls being of any well known form and representing any'two'of the rolls of the series used ,in. such machines. Mounted upon the frame A- are standards 3 having therein the vertical, extensions. 4:. The

standards 3 are provided with slots such as 5 for the accommodation-of the vertically slidable ball-bearings 6, which are vertically adjustable by means of. the bolts 7 and carry ournaled therein a lower press roll 8. J ournaled in sliding bearings 9 between the vertical extensions 4 is an upper press roll the paper to serve as aphin'ge in ledger sheets i 10.- Bolted to the tops of the vertical extensions 4: are the cross bars 11, each provided wvith an enlarged .portion adapted to fit between the vertical extensions 4 and carryin at one end the uprights. 12.. Threade through the cross bars 11 are shafts 13 proadapted to bear upon the sliding bearings 9,

.Screw 27 operated by hand wheel adjacent their upper ends with hand wheels 15 and at their upper ends with shoes 16. I ivoted in the uprights iii are pre sure arms 1? supported in the shoes in and lying at their outer end and. ai mstable tn-erealong, the weights in.

licmovably bolted to the 'lrame .i are the standards 1.) in which is a journaled and idler roll 20. vin the specific modification of the invention herein disclosed. whi h relates to a device for making loose leaf ledger sheets having a. thin hinged portion, we provide a pair of belts 21, preferably made of steel. which are trained over the upper press rolls 1t) and the idler roll 20.

Extending sidewise from the standards 3 are brackets one of wliiclrlias a projecting car 23. Slidably mounted in alined apertures in the brackets 22 is a rod 2i having atone end a plate "25 carrying the. block 26 in which is swiveled the end ot the hand The rod 2st has fixed thereon in tlie specific, form illustrated in the drawings. two collars 2E) carrying arms 30 provided at their ends with eyes 31 encircling the upper and lower reaches ofthe beltsll. just described the belts 21 may be shifted longitudinally of or held in adjusted position relative to the. rolls.

The upper and lower press rolls 8 and 10 are geared togetl1er,'as shown in Fig. 2;} and are positively driven by means of the clutch 32, gear 33 and driving gear 34. these parts being of well known occurrence in the art.

In operation the paper I in its course through the machine passes first about one drier roll then between the press rolls and. then about another. In passing between the press rolls 8 and 10 it receives the impress of the bolts 21, the paper therefore being compressed in a strip or strips along the line of these belts as shown in somewhat exaggerated form in Fig. 4. Inasmuch as these pressure devices act upon the paper while it is partly, but before it is completely dry, the belts 21 will serve to compress a portion of the already formed paper without tearing apart the fibers ormaking an indistinct or smudgy impress. Immediately after the action of the compression belts 21, the paper is preferably passed about another drier and the impress thoroughly baked in.

The invention has been shown as applied to a paper making machine. However it may be applied upon a special machine adapted to treat paper which has been dampened inorder to get it into the right condition, instead of paper in the course of its manufacture. p I

It will be clearly understood that belts, such as 21 of other materials than steel may. if desired, be used, steel or some other hard resilient material being, however, in our opinion, preferable. Moreover any number By the mechanism of belts may bev applied. and of any width. up to the length of the press rolls. The length of the. belts applied and therefore the length of the. impression surlacc.which will be. impressed upon the paper before a repeat,

of course an arbitrary matter.

\Ye have shown the idler roll 20 as mounted upon the framework of the, machine close to the stamlards 2.), but the idler rolls 20 or, it necessary. several idlers and supporting rolls might be availed of and the traveling belt, be ot any-length desired. It would also be possible to provide standards such as 19 at the. opposite sides of the standards 3 and make the belt travel completely through the press rolls, and over any number oi other rolls. before returning thereto. vFinally the. iml'iression surface of the belt or belts. such as 21 may carry a design to be imparted to the paper.

'hile we have illustrated and described one. embodiment of our invention as a device for compressing paper in a stripe or strip such as is used in a loose leat ledger hinge. we wish it to be particularly mulerstood that the invention is by no means limited thereto. ()ne of its important features is the fact that by using an endless belt as the impression surface or die. we make the impression suriace |)l2l('i'l ;lll as large as we desire, thus by providing a belt oi this characte and placing a design upon its surtace (as is well known in. connection with marking plates as shown for instance in the patent to Iii-own Yo. 1,014,035, dated January 10th. 1912) we may impart to the paper a pattern quite independent in its length of the circmnference of any roll treating the paper in the course ot its progress through the machine. or a set of small patterns of any size. the set being. it necessary, much longer than the circumference of any roll treating the paper in its progress through the machine, whereby a considerable length oi? paper is impressed before it necessary to repeat the design. we consider this broadly new.

Ive claim 1. In a. paper making machine, means to partially dry the paper. means to finish the drying thereof, a support for the paper interposed between said means, a. pressure roll adapted to bear upon the support. a pressure device structurally independent of said pressure roll and interposed between the latter and the support and adapted to travel with the paper, means to adjust said pressure device late-rally of the paper.

In apparatus of the class described,'a support, a pair of rolls journaled in the support. yielding means to cause said rolls to approach each other. another support, an idler journaled in the second support, a

- flexible belt traveling over one of said rolls and said idler, a rod! threading said belt,

eyelets supported on the rod for engaging the upper and lower reaches of the belt and manually operable means for longitudinally adjusting the rod.

3. In a paper treating machine, a pair of squeezing rolls adapted to have the paper pass therebetween, a flexible metallic pressure device adapted to pass between the compression surfaces of said rolls with the paper, and means to shift said device axially 0f the rolls or maintain it in adjusted axial position. I

4. In a paper making machine, a pair of driers, a pair of squeezing rolls located between the driers between which the paper is caused to pass, ,a traveling strip having a hard impression means to force said rolls together with a heavy pressure adapted to travel through the bite of the rolls with the paper whereby the impress of the strip is first communicated to the partly dry paper and thereafter rendered permanent.

5. In a paper making machine, a plurality of driers, a pair of squeezing rolls located intermediate adjacent driers, a pressure device relatively movable with respect to either of said squeezing rolls and adapted to travel therebetween in contact with the paper, means to accurately adjust the pressure device axially of the rolls, whereby the impress ofthe pressure device is communicated to the paper and thereafter baked in.

7. In a paper treating machine, a hard backing roll, a, hard pressure r011, yielding means to force the pressure roll against the backing 'roll 'with a heavy regulable pressure, a plurality of endlessflexible metal bandstraveling through the bite of said rolls with damp paper so as to impress said paper, and idler rolls'to support said flexible metal bands at points removed from said pressure backing rolls substantially as described.

In witness'whereof, we hereunto. subscribe our names to this specification in the presence of two witnesses.
